I got a Toki board, but the screen shows al scrambled up while MVS runs fine. This is my first cab and I'm a little in the dark how to adjust the 5v on the PSU? There are no pots for screwdriver to fit?

EDIT: adjusting the 5v didn't do anything. 15khz v-hold is glued into place, any other solutions?

Thanks, sadly this does not solve the problem...looks like a v-hold issue, but those adjustments are hard glued into place.
 
Scrambled screen is either the vhold on your chassis or there is no video ground as on some bootleg pcb’s I seen ;)

Still good to know where to adjust and measure 5v
 
You're right, it sounds like a hold issue. Just remove the glue and turn the pot. The glue is just there to keep the pot set to a general setting that will work with most games (but not all).
